HAY-PRESS.

SPECIFICATION forming part of Letters Patent No. 269,303,6lated December19, 1882,

Application filed April 15, 1882. (No model.)

To all whom it may concern I Be it known that I, JOHN MARCH, a citizenof the United States, residing in Eden, in the.

ing a toggle-joint mechanism with the ropes and pulleys, all ofwhichwill be fully and clearly hereinafter shown and described by referenceto the accompanying drawings, in which Figure 1 is a perspective view ofthe machine complete, except the capstan and its connections. Fig. 2 isa side elevation of the capstan and its releasing mechanism. Fig. 3,Sheet 2, is a top View of the capstan-releasing device; and Fig. 4-represents a top view of as much of the hay-press as is necessary toshow the mechanism for enlarging or contracting the pressing-chamber.

Arepresents the case or body of the machine; B,the doors of thepressing-chamber, of which there are two, provided with the usualfastening devices, a a

The pressing-platen G, which is arranged to move vertically inside ofthe machine, and the sliding cover on top, are madein the usual way, orsimilar to the same parts described in my PatentNo. 244,27 3, so that afurther description of them here is unnecessary. The pressingplaten G isprovided with the usual projecting parts, 0, which project through aslot or opening, D, on each side of the machine.

E representsapulley,of which there are twoone on each side of themachinefirn1lysecured by an iron strap, 0 to the parts 0.

F represents a rope (or cable or chain) fastened to the lever F by boltsor other wellknown means, f there being two levers F-- one on each sideof the machine jointed to the base by bolts 9. Each lever F is providedwith a lever, G, jointed thereto by bolts 9, and to the parts 0' of thepressing-platen by bolts 9 The rope F passes from each lever F to andunder a pulley, G, and then up in the direction of the arrow e, over thepulleys G and down in the direction of the arrow c, under the pulleys E,then up in the direction of the arrow e over the pulley G and down inthe direction of the arrow 0 under the pulleys G, and from thence in thedirection of the arrows e to the capstan H, to which it is connected inthe usual way.

The operation of this part of the invention will be understood from thedrawings. (See Fig. 1.) When the capstan is turned so that the ropesmove in the direction of the arrows the pressing-platen is moved up bythe combined action of the ropes and pulleys and the toggle-joints F G,which increase the power of the machine as the pressing-platen is movedup.

The mechanism for enlarging the pressingchamber after the bale has beencompressed, or as soon as the door is opened, so as to allow the bale tobe easily removed, is shown in Fig.4.

B B represent the doors-one on each side of the machine-andconnected toitin theusual way by hinges. ()n the inside of the pressingchamber is aswinging plate or side piece, J, hinged or jointed in any well-known wayto one side of the pressing-chamber by a bolt or other'device, I, sothat its opposite side can swing slightly to or from the side, as shown.One edge of the door B is provided with a rib, J, which, as will beseen, (when shut,) holds the side piece, J, so as to contract the sizeof the pressing-chamber,and when the door is opened, as shown by thedotted lines B it allows it to swing back, and thereby enlarge the saidchamber, so that the compressed bale can be easily withdrawn.

The capstan and its locking and unlocking mechanism are shown in Figs.2and 3, in which E represents the capstan made in the usual way. It isstrongly secured in the frame-work J J K K. To the upper part of thecapstan is rigidly secured a horizontal cross-piece, L, and the pole andblock L L is bolted thereto by a bolt, m, so it can turn easily on thecapstan, and also a hand-lever, N.

N N represent two yokes jointed by bolts 0 to the pole L. The lowerparts of the yokes are constructed so that when the device is lockedthey fit over the ends of the cross-piece L, as shown, and when unlockedthey move off and releaseit,as shown by the dotted lines. The

Ice

yokes are connected by rods or arms 0 O to the arm or lever N in anywell-known way, so as to be operated by it.

The object of the locking and unlocking device is to allow the motion ofthe capstan to be reversed, so that the pressing-platen may be moveddown without causing the horse (which may be connected to the pole L foropcrating it) to move backward.

I lay no claim here to the capstan, as Imay make it the subject of aseparate application.

I claim as my invention 1. In a hay-press, the levers or arms F, theirlower ends being jointed to the base of the machine by bolts g, so as toact as levers, and the arms G, jointed thereto by bolts g at their lowerends, and havingtheir upper endsjointed by bolts 9 to the under sides ofthe platen O, the ropes or cables F being connected to the lever F bybolts f so as to pass underthe pulleys G on each end of the platen O, incombination with the running pulley E, standing pulleys G2 G G, and asuitable capstan, substantially as and for the purposes specified.

2. In a hay-press, the door B, provided with the rib J, in combinationwith the swinging or hinged plate or side piece, J, arranged within thecompressing-chamber, substantially as and for the purposes specified.
